Title: Process for the activation of cholesterol oxidase
IPC: C12Q1/26
Filed: 1974-11-29
Abstract: Cholesterol oxidase is activated by adding a surface-active compound with lipophilic and hydrophilic properties. This method is advantageously used for detecting and for determining cholesterol and cholesterol esters in body fluids by oxidising the cholesterol with oxygen in the presence of cholesterol oxidase to cholestenone and hydrogen peroxide and detecting the hydrogen peroxide by peroxidase-catalysed oxidation of an oxidation catalyst, wherein the cholesterol oxidase is activated before it is used by adding a surface-active compound with lipophilic and hydrophilic properties. The diagnostic composition for carrying out this method is distinguished by consisting of an absorbent carrier or a plastic film which is impregnated with cholesterol oxidase, a system for detecting H2O2, buffer and at least one surface-active compound with lipophilic and hydrophilic properties, or contains these embedded in it.

Abstract: 1393128 Frequency analysis INTERNATIONAL STANDARD ELECTRIC CORP 16 Nov 1972 [19 Nov 1971] 52884/72 Heading G4H [Also in Division H4] A frequency selective signal receiver which detects the different frequencies in a compound signal applied to its input terminal E comprises reference oscillators 01-08, a decoding matrix D, a monostable multivibrator M and AND gates U1-U16. The oscillators generate the frequencies from which the input signal at the terminal E is compounded and are connected to row wires and column wires in the matrix D. Sixteen amplifiers in the matrix D each have an input connected to a row wire and an input connected to a column wire. Output terminals of the amplifiers are connected to terminals a-p so that pulses are supplied to one input of the gates U1-U16 when the sum of the waveforms applied to the two inputs of the corresponding amplifier equals zero. A circuit ND detects the zero crossings of the compound signal and enables the multivibrator to supply pulses to the other input of the gates at the zero crossings. Since simultaneity of the inputs will only occur for that AND gate which is connected to the amplifier which receives as its input signals the two frequencies corresponding to the two frequencies in the compound signal, a train of pulses will appear at one of the output terminals A1-A16.

Abstract: 1365974 Controlling the illuminated numerals on a watch ELECTRO/DATA Inc 17 Nov 1971 [23 Nov 1970] 53365/71 Heading G1A [Also in Division G3] In a battery powered electronic watch comprising a crystal controlled oscillator 11 Fig.2 followed by a frequency divider 12, counters and logic circuit type control and de-coder circuits for providing hours, mins and seconds read-out on a digital display formed by light-emitting diodes, there is provided a push button switch 4 (whereby an hours and minutes time indication is produced only on demand. In addition there are provided push buttons 7, 8 whereby the time indication may be set or corrected in accordance with a radio time signal for example. Furthermore, ambient light sensing photo-transistors 5 control via a duty-cycle controller 13 the power supply to the display diodes in dependence upon the ambient light conditions to minimize power drain. The lower the ambient light intensity the lower is the display intensity required and vice-versa. The watch may have a transparent filter cover which passes only light at the wavelength of light emitting diodes. To control the display intensity the duty-cycle controller 13 which comprises logic gates detailed in Fig.3A (not shown)) derives signals a, b, c Fig. 4 from the frequency divider outputs at frequencies f 1  = 256 HZ, f 2  = 128 HZ, f 3  = 64 HZ respectively. At ambient light levels below L1 (dimmest) current is supplied to the appropriate light emitting diodes each time all three signals are positive (curve D Fig. 4) giving a 12À5% duty-cycle. To further minimize current drain, current is supplied to the minutes display when f 1  and f 2  are positive and f 3  is low, (as curve E). When ambient light level L1 is prevalent a duty-cycle of 25% is provided (curves F and G). At light level L2 a 50% duty-cycle is provided (curves H and I) and at level L3 the hours and minutes display receive full power continuously. In curves C to I the repetition rate is at the frequency f 3 . Further power saving can be obtained by modulating the supply to the display at the divider stage frequency f 5  = 4HZ causing the display to flash and reducing the duty-cycle prevailing by 50%. In an alternative arrangement for the control of display intensity, Fig. 5 the conductivity of transistor 420 is a function of the emission of light emitting diode 436 (energized to the same level as the display diodes) while the conductivity of transistor 402 is a function of ambient light intensity. A differential amplifier 410 responds to the difference in conductivities and its output controls a transistor 432, via diode 430, whereby to control the current through L.E. diode 436 as a function of ambient light intensity. As a further alternative the output of amplifier 410 may be connected to a duty-cycle controller to reduce consumption as before.

Abstract: 1,206,629. Grab excavators. KARL BAUER K.G. 28 Nov., 1967, No. 54075/67. Heading E1F. A release mechanism for controlling the dump and drop portions of the operation cycle of a single line grab comprises a jib-supported crown block having three telescopically nesting sleeves 1, 2 and 3 of which sleeve 3 houses in radially extending slots formed therein two sets of latch balls 4, 5. The block co-operates with a tubular support mounted in so as to have a limited axial movement relative to the upper cylindrical part of the grab, which is specifically designed for grabbing out small diameter holes. The hoist rope of the grab passes up through the support and crown block and controls relative movement between the grab, the support and the block to regulate the excavating cycle of the grab. The block so operates that when the support enters the block it can pass the withdrawn balls 4, the balls 4 only being moved to a latching position beneath the lipped head of the support when the grab abuts and lifts the outer sleeve 2 to force the balls 4 inwards whilst allowing the balls 5 to lock the raised sleeve 1 to the sleeve 3. The support is then locked to the crown block so that dumping can occur when the hoist rope is slackened. Re-tensioning of the hoist rope causes the support to raise the sleeve 2 so that the balls 5 can move inwards to allow the sleeve 1 to drop and the balls 4 to move outwards in order that the support and the grab carried thereby can drop clear of the crown block on the hoist line being paid out.
